just setup my WinGate 8 with a 30 Trial PS. All works as expected.I configured to block "Social Networking" and "http://www.facebook.com" will be blocked - fine.But if i load https://www.facebook.com, the Site would be load normally - are there any solutions for this problem ?

https can be quite different (in terms of blocking) than http. It depends on how your client browsers are configured.

It sounds like probably the clients are not configured to use a proxy, and so https access is going over NAT and not via the WWW proxy. In this case https won't be filtered by the web access rules etc since it's not going through the web proxy. To get around this, you'll need to configure the clients to use a proxy.
